The spherical concentrating tank is mainly composed of four parts: the main body of the concentrating tank, the condenser, the gas-liquid separator, and the liquid receiving barrel. It can be used in the pharmaceutical, food, chemical and other industries for the concentration, evaporation, and recovery of organic solvents. Because it is concentrated under reduced pressure, the concentration time is short, and the effective ingredients of the heat-sensitive material are not destroyed. The parts in contact with the equipment are made of high-quality stainless steel, which has good corrosion resistance, durability and meets GMP requirements.
